Income Taxes

INCOME TAXES

Our tax provision for the thirteen week period endedMarch 31, 2013 consisted primarily of taxes accrued in the U.S. and foreign jurisdictions. The tax rate in the current quarter is lower due to U.S. research and experimentation tax credits generated in 2012 and recognized in conjunction with the extension of legislation enacted in January 2013. We continue to record a valuation allowance against a portion of our U.S. and foreign deferred tax assets as we do not believe it is more likely than not that we will be able to utilize the deferred tax assets in future periods.

Deferred Income Taxes

Net deferred tax assets (liabilities)were classified on the balance sheet as follows (in thousands):

	March 31, 2013			December 31, 2012
Deferred tax assets – current	$	11,760		$	12,245
Deferred tax assets – non-current	829			5,092
Other current liabilities	(71		)	(93		)
Deferred tax liabilities – non-current	(11,391		)	(17,588		)
Net deferred tax assets (liabilities)	$	1,127		$	(344	)
Valuation allowance	$	1,994		$	2,081

Unrecognized Tax Benefits

During the thirteen week period endedMarch 31, 2013, unrecognized tax benefits increased primarily due to uncertainty surrounding permanent establishment and tax credits. There were no increases or decreases in prior unrecognized tax benefits resulting from settlements with taxing authorities or lapses of statutes of limitations during the periods. We recognize interest and penalties related to unrecognized tax benefits in tax expense.
